Klang Freudenfest Oktoberfest Lager is one of three Big Brew 2017 official recipes. To view all official recipes, or to find a Big Brew event near you, visit the Big Brew for National Homebrew Day webpage. You can also view the extract version of this homebrew recipe.
The following is an excerpt from John Palmer's newly updated book How To Brew:
"The original Oktoberfest celebrated the royal wedding of Crown Prince Ludwig I and Princess Therese in 1810, and they have been celebrating ever since (some beers are worth it). The hallmark of the Oktoberfest/Märzen style is a rich maltiness but high attenuation to make it less filling. If you plan to polka for 12 hours straight, then this is your beer."
